Very slick! Love your arsenal! Tell me this, where does the temp reading come from? The surface? The core? I wonder because I know when I use my handheld one the temp varies widely depending upon where in the "vat" the probe is unless I've just stirred extremely thoroughly.
This tool is very accurate in my cheesemaking. I would agree that stirring to eliminate hot spots and create a more homogeneous mixture does help to achieve better accuracy. A lot of the time I seem to be stirring anyway.
Let's ferment something!
Bread, beer, wine, cheese...it's all good.
